Music22 is a Python2 package for musicological analysis, especially modal music and melodies. The analysis is done from audio files.

For now, it's main features are :

• Fondamental frequencies extraction (using PredominentMelody() from Essentia);
• Getting the main frequencies as peaks of the probability density function from frequencies;
• Comparing PDFs using a correlation coefficient;
• Getting a similarity matrix between melodies.

To use Music22, you need to manually install Essentia. In futur versions, it will be also possible to use TimeSide.

Then, install Music22 with the following :

pip install music22

Or using git:

git clone https://github.com/AnasGhrab/music22
python setup.py install

To use Music22 :

from music22 import modalis,scale
path = "path/to/a/folder/with/audios/wav/files/"
Kchants = modalis.melodies(path,transpose='Yes',freqref=300)

Then you can

Kchants.pdf_show()
Kchants.matrix()
Kchants.melodies[0].scale
